Abstract

Usage: in the press mechanisms of the rolling stands. The support of the pressure screw comprises a pressure screw 1 with nut 2, point 3 with bearing 8. Plate 4 with end surfaces 5 is fixed in guides 6 of the bed 7 of the stand of the rolling mill. The installation of the plate 4 between the fifth 3 and the heel 8 eliminates the bending of the pressure screw 1 due to the exclusion of the influence of the forces tangential to the surface of the heel 3, 2 silt. / s

The invention relates to metallurgical engineering, in particular to the design of pressure devices of crimping mills.

An object of the invention is to increase the durability of a screw pair.

In FIG. 1 shows the support of a pressure screw; in FIG. 2 - section aa in figure 1.

The support of the pressure screw comprises a pressure screw 1 with a nut 2 of a pressure screw, point 3, plate 4, with end surfaces 5, fixed in guides 6 of the bed 7 of the stand of the rolling mill. Bearing 8. made in the form of a half cylinder, rests with its flat surface on the pillow 9 of the rolling roll 10.

The device operates as follows.

When the metal is fed into the rolls, the rolls 9 deflect under the influence of the rolling force, as a result of which the bearing 8 is displaced along the cylindrical surface relative to the plate 4, and under the influence of the rolling moment, the pillows 9 of the rolls 10 are displaced along the rolling direction until they come into contact with

guide 6 of the bed 7, which leads to a longitudinal displacement of the bearing 8, made in the form of a half cylinder relative to the plate 4, which end surfaces 5 are fixed in the guides 6 of the bed 7 of the rolling stand, which prevents the displacement of the plate 4 relative to the heel 3 of the pressure screw 1 .

The proposed technical solution will increase the average service life of the screw pair of the pressing device of the crimping stand not less than 2 times due to the fact that there will be no bending of the pressure screw.
